erty, in the county of Clay and State of'Mis souri, have invented a new and useful Oil Filter, of which. the following is a spetnfica tion.

The present invention appertains to filters, and aims to provide a novel and improved device of that character designed especially for filtering oil, although. useful for filtering various other liquids.

It is the object of the invention to provide a filter for separating oil or other lighter liquid from water or other heavier liquid, and for removing from the oil, sediment, precipitates and other extraneous particles, and for the foregoing and other purposes, the present lter has novel and improved features of construction to enhance the utility and eiiiciency thereof.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described "and, claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, canbe made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein Figure 1 is a front view of the filter, portions being broken away.

Fig. 2 is a vertical longitudinal section looking rearwardly.

Fig. 3 is a lan view of one of the removable filter she ves or plates. I I

Fig. 4 is a detail view showing the valve operating lever.

The filter embodies a suitable casing, constructed of sheet metal or other material, and" rovided at one end with a vertical chamber l for receiving the dirty oil; The casing isprovided with a zig-zagged bottom 2 extending from one end to the other and providing transverse pockets, and a false bottom or longitudinal partition 3 of cycloidal form is provided in the casing above the bottom 2 the arched portions of the false bottom 3 hein disposed above the ridges of the bottom 2, t ere-byproviding azig-zagged passage 4 between the bottom 2 and also bottom .3' extendin from one end of'the casing to the other.

A filtering member is provided above the chamber 5, and said filtering member 20 embodies a pair of aperture 9 and 13, and a suitable fibrous'filtering material 22 disposed therebetween, the lower plate being removably held between lugs 20 carried by thepartitions 9 and 13. A bolt 23 is secured to the lower plate 21 by means of a cotter pin 23 or otherwise and a nut 23" threaded upon the bolt bears on the upper plate to clamp the material 22. A chamber 24 is provided within the casing betweenthe partitions 9 and 13' above the filtering member 20, and the filtered oil can be run from the chamber 24 to a storage tank 25 by way of a suitable connection 26 between them. The lower plate 20 has notches 21 whereby when it is turned to a certain position it can move upwardly to remove the filtering member 20.

A draw oif cock 27 is carried by the front wall of the casing in communication with the up er portion of the chamber 5 immedielowthe filtering member 20, and a glass gage 28 is also carried by said wall 'f the casing in communication with the chamber 5 to indicate the level of oil therein.

As a means for preventing the excessive accumulation of water in the chamber 10, and to prevent the water from overflowing the p artition'l2 into the chamber 11, there is provided a drain valve 29 of any suitable character at the lower end of the chamber 10, from which a valve stem 30 extends upwardly within said chamber and out said stem when raised opening the valve 29 sot-hat the water can drain out. The upper end of the stem 30 is pivoted to one arm of a lever 31 fulcrumedto the corresponding end of the easing, and a spring 32 is disposed-between said arm of the lever and the casing for depressing said arm of the lever and stem 30to level is elow a' predetermined point in the chamber 10. Hung from the other arm of the lever 31 is a hollow balancing chamber 33 which has an elbow or connection 34 extending from its bottom'and connected by a hose or flexible tube 35' with a pipe 36 connected to the corresponding end of the casing and communicating with the lower portion of the chamber 10. 'An elbow-or connection 37 connected to the top :of the balancing chamber 33 a hose or flexible tube 38 witha pipe or nipple 39 connected to'said end of the casing and communicating with the chamber 10 at a level slightly abovethe point where pipe 36 is attached. to the casing.

In operation, the dirty oil is poured or run into the chamber 1, and from the-lower plates or dia- I fitting between the partitions close the valve 29 when the water is connected by as well as the sediment and precipitates, and

the water, sediment and'other matter of greater specific gravity than the oil can be drawn oil? through.the draw off cocks 6, while those substances lighter than the oil can be drawn off through the draw off cocks 8 at the upper portions ofthe upper pockets formed by the z'ig-zagged assage 4. The oil which overflows into the tering chamber 11 will be caught and held in the depressions 15 of the shelves 14, and will filter slowl throu h the sheets 16 of filtering materia where y the 'foreign particles will be held within. said depressions. When the uppermost depression is filled with oil, the oil can overflow through the respective opening 17 into the depression of the next lowermost shelf, and so on downward, there being a sufficient number of shelves in order to prevent the oil from overflowing all of them under working conditions. The oil is thus through the draw ofl' cocks 7. From the chamber 5, the oil filters upwardly through the filtering member 20, which will prevent foreign particles from passing upwardly with the oil into the filtered oil chamber 2 1. From the chamber'24, the oil can berun into the storage tank 25 of any suitable character;

Should the water level rise above a desired or predetermined point within the chamber 10, the valve 29- will be opened automatically to drain out the surplus water. It will be noted that the water and oilwill circulate upwardly through the pipe 36, hose 35, bal- -ancing chamber 33, hose 38 and pipe 39,

whereby the level of the water in the chamber 33 and accompanying parts will, be the same as in the chamber 10, the oil in the upper portion of the chamber 33 and hose 38 being lighter than when displaced by the water due to the rise of the water level. Consequently, when .the oil is displaced by the upward movement of the water level, the increased weight imposed on the outer arm of the lever. 31 will overcome the tension of the spring 32, thereby swinging said lever to raise the valve stem 30 and open the valve 29. When the water level lowers a sulficient amount, so as to lower the water level in the balancing chamber 33, the spring 32 will again exert. itself to depress the stem 30 to close the valve 29 and raise the bal ancing chamber 33. This mechanism therefore serves to regulate the level of the water in the chamber 10 to avoid the overflow of Water into the chamber 11 which would be objectionable. The adjustment of the balancing chamber 33 anflys ring 32 is such that the spring will ordinarily overcome the weight of the chamber 33 and accompanying part when the water level is be]. ,,a predetermined point in the chamber 10, belt-when the water level rises above said point, the water in displacing the oil within her 83 will increase theto overcome the tension of the spring 32.

A steam coil 40 can be disposed below the bottom for supplying heat if desired.

Having thus described the invention, What is claimed as new 1. A. filter having a zig-zagged passage and chambers extending upwardly and communicating with the ends of said passage, said passage providing pockets, and means for drawing oif matter collecting in said pockets.
